4D flow-sensitive MRI is increasingly being used for hemodynamic analyses of cardiovascular diseases, including pulmonary arterial hypertension. PC VIPR is a time-efficient 4D flow-sensitive MRI technique, using radial undersampling, to obtain high spatial resolution data with a large volume of coverage. In this study we validated the use of PC VIPR magnitude data for the quantification of right and left ventricular volumes in a canine model of acute pulmonary arterial hypertension.
